Query Response TIME Comparison Nosqldb Mongodb with Sqldb Oracle
Penyimpanan data saat ini terdapat dua jenis yakni relational database dan non-relational database. Kedua jenis DBMS (Database Managemnet System) tersebut berbeda dalam berbagai aspek seperti per-formansi eksekusi query, scalability, reliability maupun struktur penyimpanan data. Kajian ini memiliki tujuan untuk mengetahui perbandingan performansi DBMS antara Oracle sebagai jenis relational data-base dan MongoDB sebagai jenis non-relational database dalam mengolah data terstruktur. Eksperimen dilakukan untuk mengetahui perbandingan performansi kedua DBMS tersebut untuk operasi insert, select, update dan delete dengan menggunakan query sederhana maupun kompleks pada database Northwind. Untuk mencapai tujuan eksperimen, 18 query yang terdiri dari 2 insert query, 10 select query, 2 update query dan 2 delete query dieksekusi. Query dieksekusi melalui sebuah aplikasi .Net yang dibangun sebagai perantara antara user dengan basis data. Eksperimen dilakukan pada tabel dengan atau tanpa relasi pada Oracle dan embedded atau bukan embedded dokumen pada MongoDB. Response time untuk setiap eksekusi query dibandingkan dengan menggunakan metode statistik. Eksperimen menunjukkan response time query untuk proses select, insert, dan update pada MongoDB lebih cepatdaripada Oracle. MongoDB lebih cepat 64.8 % untuk select query;MongoDB lebihcepat 72.8 % untuk insert query dan MongoDB lebih cepat 33.9 % untuk update query. Pada delete query, Oracle lebih cepat 96.8 % daripada MongoDB untuk table yang berelasi, tetapi MongoDB lebih cepat 83.8 % daripada Oracle untuk table yang tidak memiliki relasi.Untuk query kompleks dengan Map Reduce pada MongoDB lebih lambat 97.6% daripada kompleks query dengan aggregate function pada Oracle
The Collapsing Dayaknese Totem: Palm Oil Plantation and the Waning of Religiosity in West Kalimantan
For the Dayak Desa people of Kampong Nek Gambang, tapang madu (Koompassia excelsa) is believed as their totem rather than just a bee tree. Being a totem, tapang madu underwent three cultural modifications: social, religious, and psychological. In religious function, tapang madu is considered as the main media for Desa’s initiation ritual, as well as having vital position in their myth of origin. In its social function, tapang madu is also a statement of clanship, serving as a family tree which records up to nine late generations of ancestors. Relating to its social function, the tapang produces honey which is invaluable to the Dayak Desa. In its psychological function, tapang madu is protected by a collapsing-taboo. Nevertheless, research shows that even though it is considered sacred, tapang madu totem has been massively demolished by external groups and even the people of Nek Gambang themselves. This ethnographic research is aimed to understand the reason for the fall of tapang madu totem both physically as well as symbolically.

Green synthesis of MgO nanoparticles using Moringa oleifera leaf aqueous extract for antibacterial activity
Nanoparticle fabrication using plant extracts is an important alternative method because it is non-toxic, biocompatible, and environmentally friendly. In this study, green synthesis of MgO nanoparticles using Moringa oleifera leaf water extracts was conducted by mixing the extract and a solution of magnesium chloride. The product was characterized using different techniques, i.e. UV-Visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The UV-Vis spectrum of MgO nanoparticles shows an absorption at 280 nm. The size of the synthesized MgO nanoparticles ranges from 20-50 nm. The antibacterial activity of MgO nanoparticles was seen from the zone of inhibition against Staphylococcus aureus (6.3 mm) and against Escherichia coli (6 mm). MgO nanoparticles have been successfully fabricated using Moringa oleifera leaf aqueous extracts, providing an alternative method for synthesizing MgO nanoparticles.

INDEKS MASSA TUBUH (IMT) SEBAGAI FAKTOR RISIKO PADA KECURIGAAN HERNIA NUKLEUS PULPOSUS (HNP) LUMBAL
ABSTRACT
Background: Herniated Nucleus Pulposus (HNP) is a condition where nucleus pulposus protruded and pressed into canalis spinalis through teared anulus fibrosus. HNP most often affected L4-L5 or L5-S1 areas. Body mass index (BMI) is one of the risk factors that may causes the HNP. The excess BMI can affect the shape of the disc and cause an increase load on the intervertebral disc. Objectives: Knowing BMI as a risk factor on suspect HNP in the Neurological Outpatient Clinic at Abdul Manap Hospital Jambi City. Methods: This is an analitycal study using cross sectional design with 55 total samples.
